Description
The SRT-L70 temperature meter has a Pt100/Pt500/Pt1000 input. Measuring range contains temperatures: -100°C...+600°C with resolution 0,1°C. The nonlinear sensor characteristic is fully linearizated. The additional advantage of this device is automatic recognition of 2, 3 and 4-conductor connection. There is a possibility of access to inner registers via RS-485 interface. The regulator features 3 relay outputs (2 NO and 1 NO-NC). The power supply is realized by build-in pulse feeder, which gives the correct supply in very wide range of voltages 19V...90V DC; 16V...70V AC or 85V...260V AC/DC. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
